EllipsoidGeodesic

new Cesium.EllipsoidGeodesic(start, end, ellipsoid)
@cesium/engine/Source/Core/EllipsoidGeodesic.js 286

Initializes a geodesic on the ellipsoid connecting the two provided planetodetic points.
Name Type Default Description
start Cartographic optional The initial planetodetic point on the path.
end Cartographic optional The final planetodetic point on the path.
ellipsoid Ellipsoid Ellipsoid.default optional The ellipsoid on which the geodesic lies.

Members

readonly ellipsoid : Ellipsoid
@cesium/engine/Source/Core/EllipsoidGeodesic.js 310

Gets the ellipsoid.

readonly end : Cartographic
@cesium/engine/Source/Core/EllipsoidGeodesic.js 350

Gets the final planetodetic point on the path.

readonly endHeading : number
@cesium/engine/Source/Core/EllipsoidGeodesic.js 378

Gets the heading at the final point.

readonly start : Cartographic
@cesium/engine/Source/Core/EllipsoidGeodesic.js 338

Gets the initial planetodetic point on the path.

readonly startHeading : number
@cesium/engine/Source/Core/EllipsoidGeodesic.js 362

Gets the heading at the initial point.

Methods

interpolateUsingFraction(fraction, result) → Cartographic
@cesium/engine/Source/Core/EllipsoidGeodesic.js 411

Provides the location of a point at the indicated portion along the geodesic.
Name Type Description
fraction number The portion of the distance between the initial and final points.
result Cartographic optional The object in which to store the result.
Returns:
The location of the point along the geodesic.

interpolateUsingSurfaceDistance(distance, result) → Cartographic
@cesium/engine/Source/Core/EllipsoidGeodesic.js 430

Provides the location of a point at the indicated distance along the geodesic.
Name Type Description
distance number The distance from the initial point to the point of interest along the geodesic
result Cartographic optional The object in which to store the result.
Returns:
The location of the point along the geodesic.
Throws:
  • DeveloperError : start and end must be set before calling function interpolateUsingSurfaceDistance

setEndPoints(start, end)
@cesium/engine/Source/Core/EllipsoidGeodesic.js 395

Sets the start and end points of the geodesic
Name Type Description
start Cartographic The initial planetodetic point on the path.
end Cartographic The final planetodetic point on the path.
